Adipic acid 99.8+%. extra pure

Chemical Properties
Adipic acid (systematic name: hexane-1,6-dioic acid) is an aliphatic dicarboxylic acid with the molecular formula C₆H₁₀O₄.
It consists of a straight chain of six carbon atoms with a carboxyl group (-COOH) at each end.
Key characteristics:

• Molar mass: 146.14 g/mol

• Physical form: white, crystalline powder

• Melting point: approx. 152 °C

• Solubility: moderately soluble in water, readily soluble in alcohol and certain organic solvents

• pKa values: ~4.4 and 5.4 (dibasic acid)

• CAS number: 124-04-9

Production Process
Industrial production of adipic acid is typically carried out by oxidizing cyclohexanol and cyclohexanone, often using nitric acid as an oxidizing agent.
Other modern methods include catalytic oxidation processes and biotechnological routes (fermentation) for a more sustainable production approach.

Industrial Applications
Adipic acid is an important bulk chemical in the polymer industry. Main applications include:

• Nylon production
  It is an essential raw material for the production of nylon 6,6.
  In this process, adipic acid is condensed with hexamethylenediamine to form polyamide chains. This nylon is used in textiles, technical fibers, cable ties, automotive parts, and machine components.

• Plasticizers and lubricants
  Esters of adipic acid (adipates) are used as plasticizers in PVC and other plastics, improving flexibility.
  Certain adipates are also used as base components for lubricants that perform well at low temperatures.

• Polyurethane production
  Adipic acid is used in the manufacture of polyurethane foams, coatings, and elastomers, where it contributes to flexibility and chemical resistance.

• Resins and coatings
  In combination with other diols or polyols, adipic acid is used to produce polyester resins, for example in powder coatings or industrial paints.

4. Safety and Handling
Adipic acid is relatively stable and non-volatile, but it can cause skin and eye irritation upon direct contact.
It is typically stored in dry, well-ventilated areas in moisture-resistant packaging.

Buying Adipic Acid from a Laboratory Supplier
